A sample of gas has a volume of 526 mL at 346 mmHg and 35.0°C. Determine the moles of gas.​
Furkat [3]

Answer:

The moles of gas is 0.009474 moles.

Explanation:

Given that,

Volume = 526 mL

Pressure = 346 mmHg

Temperature = 35.0°C

We need to calculate the moles of gas

Using formula of ideal gas

n=\dfrac{PV}{RT}

Where, P = pressure

V = volume

R = gas constant

T = temperature

Put the value into the formula

n=\dfrac{\dfrac{346}{760}\times0.526}{0.08206\times(35+273)}

n=0.009474\ moles

Hence, The moles of gas is 0.009474 moles.
